WILLIAM H. BRADLEY, OF HALF MOON BAY, CALIFORNIA.

OIL-BURNER.

To all whom it may concern:

Be it known that I, VVILLIAM H. BRADLEY, a citizen of the United States, residing at Half Moon Bay, in the county of San Mateo and State of California, have invented new and useful Im rovements in Oil-Burners, of which the fo lowing is a specification.

This invention relates to portable burners, and pertains especially to such fluid or hydrocarbon burners as are adaptable to stoves, ranges and the like.

A purpose of my invention is to provide a burner embodying means whose function is to assist in the combustion of fluid fuel, and which means is entirely separate from the oil feeding mechanism thus facilitating the operation and simplifying the construction of the burner.

A further purpose is to provide a generator in combnation with an oil burner, so positioned and constructed that there is practically no residual soot or smoke; and to provide means whereby the combuston of the fuel is under perfect control, and whereby the burner elements may be readily adjusted to adapt the burner to the use of thick or thin fuels. The invention consists of the parts and the Construction and combination of parts as hereinafter more fully described and claimed, havin reference to the accompanying drawings, in which- F igure 1 is a sectional plan view of the burner in a fire box of a stove. Fig. 2 is a side elevation of the burner and fire box shown in Fig. 1. Fig. 3 is a sectional end View of the burner and fire box shown in Fig., 1.

The burner as actually 'constructed and successfully operated embodies an oil pot or pan 2 of suitable size and shape, though as represented it is oblong, and has upwardly extending end walls 3, upon which is removably seated a steam or gas generating cylinder 4, preferably formed of standard iping having heads 5 and 6, and exteu ing lengthwise above the burner pan 2.

Projecting through and Secured in one of the sides of the pan is a small tube 7 upon the outer end of which is screwed a T connection 8, and in the outer opening of this is a removable plug 9. Occasionally this plug 9 may be taken out, and a rod or wire inserted whereby the tube 7 may be cleared of sediment should any be deposited.

To the transverse branch 10 of the T con- Specification of Letters Patent.

Patented sept. 13, 1910. Serial No. 532389.

nection 8 is connected a fuel supply pipe 11, carrying any suitable form of valve at 12, referably this valve is provided with a safety lock or latch 13 so that it may not be tampered with, or accidentally moved after having been adjusted to suit the fuel being used.

The cylinder 4 is provided at its head 5 with a pipe section 14, and a joint 15, and I supply Water from a suitable source not shown, to the cylinder and connections 14- 15 through a sight feed valve 16 of such character that the Volume of water adnitted may be accurately regulated.

In operation, fuel is turned on at valve 12 and ignited in the pan 2, and then the watercontrolling valve or regulator 16 is slightly opened, so that drop by drop, water is ad'- mittecl to the generator 4, and this, bein located centrally above the pan 2, is heated e by the flame converting the water in the generator 4 into steam which passes out of cylinder head (i into a horizontal conductor 17 extending lengthwise above the adjacent side of the pan 2. The conductor 17 is connected, as at 18, across the end of pan 2, to a spray arm 19 paralleling the arm 17, but on the opposite side of the pan 2, the arm 19 being perforated at 20-20 and dirccting jets of steam inwardly and slightly downwardly toward the pan 2, and in prox imity to the discharge of the fuel tube 7 An important element in the burner is a hood 21 having a curved, perforated upper portion, and vertical sides 23-23, the bot tom edges of which rest in seat lugs 24 cast or formed upon the pan 2. The purpose of the hood is to sonewhat confine the flame of combustion, and cause it to have a swirling, rotary notion around and around the cylinder 4 due partly to the tendency of the rising fiame, the cylindrical contour of the hood, and mostly to the impulse of the steam generated in the cylinder 4 escaping through the perforations 20 in the spray arm 19. In this manner of causing the flame to revolve about a horizontal axs over the pan 2 the combustible gases generated are thoroughly commingled and totally consumed, no residue accumulating save heavy non-burning minerals sometimes found in the fiuids; and when such residue does occur it may be removed through an opening 25 formed in one end of the pan 2. Air to aid combustion is admitted through the side wall 23 of the hood 21 via an aperture 22 extend- `ling the admission of fiuid to the generator,

I am enabled to produce a liqnid fuel burner of maximum efiicency, devod of dangerous complex parts or adjustments, and easily,

knocked down and packed for shipment. As shown the burner may be applied, as desired, in a fire-box A of a stove.

Having thus described my invention, What I claim and desire to secure by Letters Patent isl. The combination in an oil burner having a fuel nozzle, of a pan, a superposed horizontal cylinder, means to deliver fuel to the nozzle so that it may discharge transversely of the pan and beneat-h the cylinder, a perforated inclosure for the cylinder and products of combustion, said nclosure being outside of and spaced from the cylinder and adapted to retard the escape of the products of combustion, means to admit Water to the cylinder, and a steam pipe leading from the cylinder and having jets discharging into the pan contiguous to said nozzle.

2. The combination in an oil burner having a nozzle, of a pan, a superposed horizontal cylinder, means to deliver liquid fuel to the nozzle so that it may be delivered transversely of the pan and beneath the cylinder, a perforated inclosure for the cylinder, said inclosure being spaced from the cylinder and adapted to retard the escape of the products of combustion from thereabout, means to admit Water to the cylinder, and a steam pipe exte'ndng from one end of the cylinder along both sides and across the other end of said cylinder, the terminal, side pipe lying above the fuel nozzle and dischargng steam jets into the pan contiguous to said nozzle.

3. The combnation in an oil burner, having a nozzle, of a pan, a superposed horizontal cylinder, means to deliver liquid fuel transversely of the pan and beneath the cylinder, means to admit Water to the cylinder, a steam pipe extending from one end of the cylinder parallel With both sides thereof and across the opposite end thereof, the terminal side pipe lying above the fuelnozzle, and having steam jets into the pan contiguous to the fuel nozzle, and an arched, perforated hood supported from the pan sides and inclosing the cylinder.

4. The co-mbination in an oil burner, having a nozzle, of a pan, a superposed horizontal cylinder, means to deliver liquid fuel transversely of the pan and beneath the cylinder, means to admit Water to the cylinder, a steam pipe extendng from one end of the cylinder parallel With both sides thereof and across the opposite end thereof, the terminal side pipe lying above the fuel nozzle, and having steam jets into the pan contiguous to the fuel nozzle, and an arched perforated hood supported from the pan sides and inclosing the cylinder, said hood having an open air admission slot above the fuel nozzle.

5. The combination in an oil burner, having a nozzle, of a pan, a superposed horizontal cylinder, means to deliver lquid fuel transversely of the pan and beneath the cylinder, means to adnit Water to the cylinder, a steam pipe extending from one end of the cylinder parallel With both sides thereof and across the opposite end thereof, the terminal side pipe lying above the fuel nozzle, an arched perforated hood supported from the pan sides and nclosing the cylinder, said hood having a curved top and parallel sides and an open air admission slot above the fuel nozzle, and a controlling lock for the 'uel supply.

In testimony Whereof I have hereunto set my hand in the presence of two subscribing witnesses.
